Hi! I've got a problem!

Hi! I've got a problem with my Camtasia 8. Whem I try to export file in 4k format, the progressing bar stop in the middle of the render. I did it several times, , but never complete. How can I fix the problem?

Camtasia Studio 8 does not support 4k resolutions as the maximum Studio resolution that it could work with was 2048x2048. We did not add 4k support to the program until Camtasia 9. In reality, due to Camtasia Studio 8's 32-bit nature, we do not recommend working with content that is any larger than 1920x1080 (1080p). If you use 1080p source material, add it to a new project, then produce to 1080p, do you have the same issue?
